' 9 Claims. (01. 40-125) Theinve'ntion relates to a collapsible display'device. of the type in which a length of flexible material is adaptedto be-rolled orwrapped about a rod or roller to constitute a compactconstruction, economizing in space for storing and transportation andwhich can be readily distended with the flexible material stretchedtaut. The primary object of the invention is to provide'a simplifiedform of construction of the type outlined which will feature a-highdegree of compactness; the utilization of the least possible amount ofmaterial and at the same time to give the requisite structural strengthto the construc:

tion'asawhole.

Still another object of the'invention and still featuring compactness inconstruction is to-pro. vide a simple means for bracing the structureagainst distorting strainsand to provide for a wide spreading form ofbase support for-holding thestretched material in upright position. 7

Various other objects and advantages of the invention-will be in partobvious from an in- 'spectionz of-the accompanying-drawing andin partwill be more fullyset forth in the following. particular description ofone form of mechanism embodying thetinvention, and the invention alsoconsists in certain new and novel feaftures of: construction andcombination of parts hereinafter set forth and claimed.

Inthe accompanying drawing: Fig. '1 is a view in rear elevation showinga preferred embodiment; of the invention distended to sh'owrit in itsoperative position and with the parts broken away; 1

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. landlookingin the direction indicated by the arrows; c 1 Fig. 3 is adetailed sectional view taken on the line 33 of Fig.' 2 and=showing thestretcher about to be slid into the roller bar; and

Fig. 4 is a view in elevation of the structure shownin thepreceding'figures rolled in collapsed and housed position.

Referring to the drawing there is disclosed a .length 10 of flexiblematerial which may be paper,

one side 12 of which is flatand to this flat side is permanently securedas by gluing or tacking the/upper edge of the material 10.- I

At the lower edge of the material 10 there is secured a similar bracefor giving rigidity to this portion of the fabric. This brace,hereinafter referred to as roller 13, is of somewhat elliptical form asshown in Fig. 2 with a fiat side 14 to which the lower edge of thefabric -10 is secured. Atthe central portion of the underside of thebrace 11 there is provided a socket 15 and similarly .theroller 13 isprovided with an oppositing socket 165. A stretcher 1'7. ispositioned-with its opposite ends inserted respectively in the sockets15 and lfi and the parts are so proportioned that the stretcher willhold the flexible material-taut when in the distended position shown inFigs. 1 and 2. The stretcher is formed of two parts, a tubular part 18and a rod 19; the rod 19 being provided adjacent one end with a collar20 and positioned between the collar 20 and a bead 21 formed on theadjacent end of the tube 18 is a distendable spring 22. It will be notedfrom the construction as shown in Figs. 1 and 2 that the spring 22 actsto, force the parts 18 and 19 in opposite direction thus placing theflexible material 10 under spring tension.. The stretcher is so arrangedthat when the parts 18 and;19 have been demountedfrom each other thelong upper portion 23 of rod 19 may be reversed from the position shownin Fig. 1 and telescoped within the open end of tube 18 so that thetelescoped parts are reduced in length and the partsare so proportionedthat when so telescoped they may be contained within the bore 24 whichextends axially .through the roller 13. Y,

1 To one 'side of' the bore the portion of the rolleropposite the flatside 14 is provided with a groove 23 in which is contained or at leastpartially contained a foot 26, the end adjacent the socket 16 beingpivotally mounted in place on pin 27. Instead of this pivotal mountingof the foot 26, it is obviously within the scope of the disclosure toprovidea transverselyextending bore or socket 28 indicated in dottedlines in Fig. 2 into which the end of the foot may be positioned with afriction tight fit when it is desired'to have the 'foot extend laterallyfrom the roller to obtain the wide spreading support to the device asa-whole as indicated in the showing in Fig. 1. V I

In operation and assuming the parts to be in the position as shown inFig. 1, itisapparent that the flexible material 10 is stretched taut inits plane to expose the characters on its front side and that when sopositioned the material 10 acts to conceal its bracing parts positionedat .the rear of the material. There will usually be sufficient play inthe flexible material to permit the removal oi-the stretcher 17 and forthis purpose it is noted that the socket 15 is comparatively shallow.Should difliculty be experienced in removing the stretcher, it is simplynecessary to hold two parts of the same and by moving the parts towardseach other and against the resistance of the spring 22, one or the otherend of the stretcher may be readily removed from its associated socket.When the stretcher is dismounted, the foot 26 is either swung back intoposition housed within the groove 25 or, in case the socket form ofsupport is provided for the foot, it is simply withdrawn longitudinallyfrom the associated socket at 28 and positioned in the groove 25. Thetwo parts of the stretcher are then separated, reversed and retelescopedas hereinbefore indicated and the telescoped assembly is then insertedin the bore 24, as indicated in Fig. 3. The length of flexible material10 is then wrapped about the roller in the manner of a shade roller asshown in Fig. 4 and preferably the parts are so proportioned that theflat side 12 of the upper brace 11 will face with the flat side 14 ofthe roller 13 so that there is finally obtained the smooth, somewhatelliptical wrapped construction shown in Fig. 4 and which may be readilycontained in a mailing tube or other container.

By means of a device of this character it is possible to provide a formof display device which can be made much larger than similar construetions now known; which will have a neat, substantially rigid appearancewhen distended into stretched position and which can be provided with along supporting foot which will tend materially to one side to maintainthe structure supported in its upright display position. When rolled forstorage or transportation, there is presented a neat package withoutprojections which might catch in other articles with similar projectionsand there is provided a structure which can be easily handled andquickly mounted in position thus providing an article which isparticularly adapted for lecture and other purposes where difierentcharts and display matter have to be quickly set and dismounted, oneafter the other.

The present disclosure particularly features a structure which when inwrapped position is entirely self-contained and forms a compact package.
